This filecontains some informationabout aexposure to second-hand smoke.How manyobservations are there in thisfile?There are 3 columns of data each containing 40 observations so in total thereare 120 observations.In this file, there are three variables, labeled Smokers, ETS, and No ETS. The dataset was collectedfor a study of second-hand smoke. Thesample data consists of themeasured serum cotinine levelsinthree different groups of people.The NOETS group lists the cotinine levels for subjects who are nonsmokers and have no exposureto environmental tobacco smoke at home or work.The ETS group lists cotinine levels for subjects who are nonsmokers exposed to tobacco smoke athome or work.The SMOKERS group lists cotinine levels for subjects who report tobacco use.Serum cotinine is a metabolite of nicotine, meaning that cotinine is produced when nicotine is absorbed bythe body. Higher levels of cotinine correspond to higher levels of exposure to smoke that containsnicotine.2.What results do you expectto find in this data?We would expect the smoker group to have the highest levels of cotinine levelsfollowed by ETS and NOETS groupPart II.Descriptive Statistics3-6Generate descriptivestatistics for all three groupsof people and complete theVariableSampleMeanSampleStandardDeviationSample SizeSmokers172.48119.5040
